论文摘要
碳碳（C-C）偶联反应是在精细化学物质，农业化学物质和药物的生产中广泛使用的反应。在我们最近的贡献（绿色化学，2019，21，5284-5290）中，氧化热（CU2O）纳米球被证明是末端碱（例如苯基乙烯）的C-C偶联反应的有效催化剂。具体而言，Cu2O纳米球被证明可以成功地催化苯乙烯的氧化C-C同偶联反应，形成偶联产物二苯基二乙烯（DPDA）。但是，这些Cu2O纳米催化剂需要相对较高的温度〜110 0c。在此，我们报告说，在Cu2O上装饰（即Cu2O-PD）上构建的光催化剂可以使用可见光作为能量输入，并成功地催化了在大气温度和压力反应条件下苯基乙烯的氧化氧化同偶联物的可见光。通过在存在下并且没有可见光的情况下，通过比较氧化均匀反应的比较来显示这一点。我们的发现表明，通过Cu2O-PD纳米球的光催化剂是逻辑替代品，朝着更高效和可持续的工业过程迈进。
Carbon-carbon (C-C) coupling reactions are widely used reactions in the production of fine chemicals, agrochemicals, and pharmaceuticals. In our recent contribution (Green Chemistry, 2019, 21, 5284-5290), cuprous oxide (Cu2O) nanospheres are shown to be efficient catalysts for C-C coupling reactions of terminal alkynes such as phenylacetylene. Specifically, Cu2O nanospheres are shown to successfully catalyze oxidative C-C homocoupling reaction of phenylacetylene to form a coupling product, diphenyl diacetylene (DPDA). However, these Cu2O nanocatalyst requires a relatively high temperature of ~110 0C. Herein, we report that photocatalysts built on hybrid palladium nanoclusters decorated on Cu2O (i.e., Cu2O-Pd) can utilize visible light as energy input and successfully catalyze oxidative homocoupling of phenylacetylene at atmospheric temperature and pressure reaction condition. This was displayed by the comparison of oxidative homocoupling reactions both in the presence and without the presence of visible light. Our findings indicate that photocatalysts through Cu2O-Pd nanospheres present to be a logical substitute, moving toward more efficient and sustainable industrial processes.
